Notwithstanding its successful vaccination campaign (which has been often put in contrast to EU's comparatively sluggish record), the United Kingdom is currently suffering another wave of the coronavirus pandemic, driven by the very contagious 'delta' (a.k.a. 'Indian') variant.
How this came to be is well known, and clearly linked to political decisions made by the UK Government. But the consequences could be very dire for continental Europe.
Indeed (see map below), the countries in the EU currently most affected by the new surge in cases are exactly those who recently welcomed UK tourists with few restrictions or none at all: Portugal and Spain. From there, as recent history demonstrates, it's only a matter of time before the fresh pandemic wave sweeps across the continent.
After last spring's third wave of covid-19 in Europe was driven by the 'alpha' variant of the virus that originated in England, it's now the second time in half a year that the UK is the gateway for a pandemic wave affecting the continent. The main explanation for this recurrent hazard is the continued recklessness in managing this health crisis by the British authorities.
